Ghost pepper

I have about 12 plus peppers on my ghost pepper plant. They are a little over an inch in length and still green. I went to pick one and noticed that it was soft as the others on the plant. I proceeded to bite into it and it was not hot at all. Was wandering why they were soft and why no hear. Any help would be appreciated

There are some specifics needed in care to grow Ghost Peppers.
The fruit are quite delicate, so your description of soft seems right.
I do want to mention that in my research, I have found numerous reports of people purchasing seed that is represented as Ghost Pepper seed, and that they are not either of good quality or not Ghost Pepper seeds at all.
Make sure you purchase from reputable sellers.
